Currently the entities store their configurations into a display list.
Adapt this such that the code can be configured into a body directly,
allowing greater flexibility and control of the content.
All users of vsp1_dl_list_write() are removed in this process, thus it
too is removed.
A helper, vsp1_dl_list_get_body0() is provided to access the internal body0
from the display list.

Adopt the SPDX license identifier headers to ease license compliance
management. All files in the driver are licensed under the GPLv2+ except
for the vsp1_regs.h file which is licensed under the GPLv2. This is
likely an oversight, but fixing this requires contacting the copyright
owners and is out of scope for this patch.
While at it fix the file descriptions to match file names where copy and
paste error occurred.

We don't need to walk the pipeline when propagating the alpha value as
all the information needed for propagation is already available from the
pipeline structure.

Modules write register values to the active display list pointed to by
the pipeline. In order to support preparing display lists ahead of time,
pass them explicitly to all configuration functions.

Pixel color components can be scaled using either bilinear interpolation
or a multitap filter. The multitap filter provides better results, but
can't be selected when the alpha layer need to be scaled down by more
than 1/2.
Disable alpha scaling when the input has a fixed alpha value, and
program the UDS to output a fixed alpha value in that case. This ensures
the multitap filter will be used whenever possible.

The VSP1 is a video processing engine that includes a blender, scalers,
filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.
Due to the configurable nature of the pipeline the driver implements the
media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.
Only the read pixel formatters, up/down scalers, write pixel formatters
and LCDC interface are supported at this stage.
